Experience the World’s Tallest Sea Bridge Observation Deck: Cheongna Sky Bridge Opens on May 7, 2026!

The Incheon Free Economic Zone Authority announced on April 27 that the Cheongna Sky Bridge observation deck — now certified by the Guinness Book as the world’s highest sea-bridge observation deck at 184 m (about 604 ft) — will open on the 7th of next month.

Officials say the sky and sea observation decks and a traveler center will open on the 7th, with safety inspections and trial runs to follow. The hands-on attraction “Edge Walk” is scheduled to begin operations on the 15th.

The sky observation deck and the Edge Walk require paid admission; the sea observation deck and waterfront areas are free to the public. Tickets are 15,000 KRW (about $11.25) for the sky deck and 60,000 KRW (about $45.00) for the Edge Walk experience (which includes sky deck access). Incheon residents receive a 50% discount.

To boost tourism, the authority plans to program concerts and cultural events in the waterfront spaces, turning the area into a lively destination beyond just a photo op.

Cheongna Sky Bridge “The Sky 184”

The Sky 184 complex on Cheongna Sky Bridge (the Third Yeonryuk Bridge) includes a sky observation deck, a rooftop deck, a sea observation deck, waterfront areas, and a traveler center — basically everything you’d want for a dramatic day out by the sea.

Perched at 184.2 m (about 604.3 ft) above sea level, the observation deck now claims the title of the world’s highest sea-bridge observation deck. That tops the previous record — the Penobscot Narrows Bridge deck in Maine at 128 m (about 420 ft) — and has been officially certified by the World Record Committee (WRC).

Standing at a height similar to a 60–67–story building, the deck delivers sweeping panoramas of the Yellow Sea. On clear days you can spot the Incheon Bridge and Yeongjong Bridge and even Seoul’s Namsan Tower and the Lotte World Tower in Jamsil. The main tower is shaped like a gate, symbolizing Incheon International Airport as a global gateway, and the structure is strikingly sculptural.

The observation area at the top of the main tower covers roughly 165 m² (about 1,777 sq ft) and limits visitors to around 40 at a time for a comfortable experience. A dedicated 15-seat elevator takes guests from ground level up to the deck.

But the real showstopper is the “Edge Walk” — a narrow path outside the observation tower that lets you literally walk the edge. Secured to a single safety line, the Edge Walk is an extreme, hands-on experience and the first attraction of its kind on a sea bridge anywhere in the world. Looking down you’ll see the Yellow Sea and cars crossing below, with transparent glass floors at several points for an extra thrill.

Hours are 10 a.m. to 6 p.m. Professional guides accompany participants for safety. Hours may change due to weather, so check ahead before you go.

Unlike car-only spans such as the Incheon Bridge or Yeongjong Bridge, Cheongna Sky Bridge was designed for pedestrians and cyclists. A 3.5–4 m (about 11.5–13.1 ft) wide combined bike-and-pedestrian lane runs along the bridge, letting locals cross between the two cities on foot or by bike and enjoy the sea breeze. The bridge is already becoming a key section of the 120 km (about 75 mi) cycling route linking Jeongseojin to the Ara Canal.

The lower observation deck and a 1,516 m² (about 16,325 sq ft) waterfront area are open without reservation or admission. The lower level can accommodate about 280 people and features a seaside walking deck. At night, a media facade and LED columns put on a dazzling light show.

How to get to Cheongna Sky Bridge

If you’re coming from Cheongna by public transit, get off at Cheongna International City Station on the Airport Railroad. During the opening period, a dedicated shuttle bus running from a stop near Exit 1 to the observation entrance provides the fastest connection, typically every 15–20 minutes.

You can also take city buses 701, 702 (GRT), or 202, get off near Cheongna International City Station or a nearby terminal, and walk about 10–15 minutes along the connecting walkway to the observation deck.

From the Yeongjong side, get off at Yeongjong Station on the Airport Railroad and take the Jung-gu public bus (Yeongjong loop). Get off at the Third Yeonryuk Bridge starting stop to reach the park beneath the observation deck.

Unique seaside attractions

Across Korea, dramatic seaside observation decks keep popping up and drawing travelers. In Gangwon Province, the Baekseom Sea Observation Deck in Goseong perches dramatically over the water near Geojin Port.

The Baekseom deck in Geojin-eup, Goseong County, feels like a hidden gem at the northern edge of the East Sea. Once part of a military zone, public access was limited for years, leaving the waters remarkably pristine.

The deck sits about 25 m (about 82 ft) above sea level and extends roughly 137 m (about 450 ft) out from the coastal road. Walk the deck and watch white waves crash below while you peer into the clear East Sea. Transparent acrylic railings give unobstructed views of dramatic rock formations like Haegumgang and Geumgudo.

The island encircled by the deck, Baekseom, earned its name because seagull droppings once made it look white. The contrast of jagged rocks, the pale island, and the blue sea is striking. The adjacent coastal road is a popular scenic drive, and nearby Geojin Port is perfect for fresh seafood.

Goseong isn’t served by train, so start from Geojin Intercity Bus Terminal. Take an intercity bus from Seoul (East Seoul Terminal), Sokcho, or other cities to Geojin, then walk along the coastal road for about 20–25 minutes to reach the deck.

If you drive, search your navigation system for “Baekseom Sea Observation Deck” or “Geojin Baekseom.” A small parking area sits on the road directly across from the deck.

On the south coast, Busan’s Oryukdo Skywalk is another adrenaline-friendly spot. Perched at the tip of a 35 m (about 115 ft) cliff in Yongho-dong, Nam District, the U-shaped cantilevered deck lets visitors look straight down at crashing waves through a transparent glass floor.

The floor is made of three layers of 12 mm (about 0.47 in) high-load bulletproof glass. Walking on it with shoe covers is a thrill many say beats amusement-park rides. From the Skywalk, you get a panoramic view of six islands — Bangpae Island, Sol Island, Suri Island, Songgot Island, Gul Island, and Lighthouse Island — collectively known as Oryukdo. At low tide you’ll see five islands; at high tide six — a natural quirk you can witness in person.

Admission is free, though access may be restricted during severe weather for safety reasons.

The Oryukdo Skywalk is easy to reach by bus. From Busan Station’s bus stop, take bus 27 and get off at the terminal stop, “Oryukdo Skywalk.”

You can also exit Busan Metro Line 2 at Kyungsung University–Pukyong National University Station, use Exit 5, and take buses 24, 27, or 131, or the Nam-gu 2 or Nam-gu 2-1 village buses from nearby stops to reach the Skywalk terminal.
